ABSTRACT

A method of operation of a transaction collection system includes: initializing a sniff daemon on the POS terminal; determining a sales transaction on the POS terminal; recording a transaction document of the sales transaction on a memory of the POS terminal; collecting the transaction document from the memory with the sniff daemon; and providing the transaction document for interpretation on an external system.

FIELD OF INVENTION

This invention relates generally to a transaction data collection system, and in particular to collecting transaction data from a point of sale system.

BACKGROUND

In retail environment, a point of sale (POS) system typically is used at a checkout counter. The POS system may include individual POS terminals at each counter. The transaction between a consumer and a store generally occurs at the POS terminal. The POS terminal can act as a credit card terminal. A consumer's credit card can be swiped at the POS terminal or a peripheral attached to the POS terminal.

For some of the POS systems, the transaction information is printed on a receipt. A copy of the receipt can be kept in the store or given back to the consumer. Traditional POS systems are primarily used to execute sales of goods and services. The POS systems can print receipts and record transactions. However, commercial pressure requires the traditional POS systems to be improved to better serve the customers and the sellers.

Thus, a need remains for an effective methodology to collect transaction information from a POS system.

DISCLOSURE OF INVENTION

The present invention provides a method of operating a transaction collection system including: initializing a sniff daemon on a point-of-sale (POS) terminal; determining a sales transaction on the POS terminal; recording a transaction document of the sales transaction on a memory of the POS terminal; collecting the transaction document from the memory with the sniff daemon; and providing the transaction document for interpretation on an external system. The method above can also include interpreting the transaction document to determine a field entry and sending a message to an external system based on the field entry. The interpretation can be based on an optical character recognition. The interpretation can be preformed on the POS terminal or a collection server system such as a web service server.

For example, a method of operating the transaction collection system via the collection server system can include: determining a transaction document from a POS terminal; optically recognizing the transaction document to determine a sold item associated with the transaction document; matching the sold item within an item list; and recording the sold item on the web service system.

For example, the POS terminal can include: a non-transitory memory; a POS application for executing a sales transaction; a printer driver for spooling a transaction page based on the sales transaction onto the non-transitory memory for printing; and a sniffer module for sniffing the transaction page.

A transaction collection system is also disclosed including: a printer; a POS terminal with a run-time sniffer daemon, the POS terminal configured to print a transaction document to the printer, capture the transaction document with the run-time sniffer daemon, and provide the transaction document for optical recognition; and a collection server system configured to: determine the transaction document from the POS terminal, optically recognize a sold item entry from the transaction document, match the sold item entry within an item list, and record the sold item entry on the collection server system.

Some embodiments of the invention have other aspects, elements, features, and steps in addition to or in place of what is described above. These potential additions and replacements are described throughout the rest of the specification

DETAILED DESCRIPTION

A POS terminal can be a computer system with Internet access. The transaction information can be stored on a local database on the POS terminal. The local database can be synchronized with a server in batches periodically. The transaction information may also be printed on a printer via a printer driver on the POS terminal.

It has been discovered that effectively collecting and utilizing transaction data available to POS systems can greatly benefit advertisers and promoters. Existing POS systems have proprietary interfaces, making it difficult to extract and collect the transaction data thereon. Further, data that is transferred out of the POS terminal can often be encrypted, making it difficult for an outside device to intercept the messages going out of the POS terminal.

The present invention relates to a transaction collection system and methods of capturing transaction data from a point of sale (POS) system. The present invention utilizes a background process running on the POS system to sniff and collect the transaction data from a printer driver, a print queue, a local database, a batch backup process, or any combination thereof. When collecting the transaction data from any of the above processes or any combination of these processes, the transaction data can be cross-verified. Some of the methods described above can by-pass the encrypted channels of the POS terminal's internal communication system.

The background process can be a modified printer driver that captures printer data, including page description language or printed image data. The background process can also be a communication module that reads the local transaction database on the POS or intercepts the batch updates from a local transaction database to an external database.

The invention can involve a thin layer of software that sits on a POS computer and intercepts receipt print queue contents. Each transaction typically results in a paper receipt being printed. The transaction collection system can capture the receipt images by using a modified print-queue driver, or other suitable sniffing techniques. Once the receipt image is obtained, the transaction collection system can run optical character recognition on it to capture complete details of the transaction it represents. This information includes, amongst other things, the items (SKUs) in the transaction, the price per SKU, total price of transaction, time and place information, as well as any payment information that might be present.

FIG. 1 illustrates a transaction collection system 100, in accordance with an embodiment of the invention. The transaction collection system 100 can include a point of sale terminal (POS terminal) 102 in communication with a collection server system 106 through a network channel 110.

The item track module 434 can match the item entry 436 identifying a recognized sold item from within the item list 438. The item track module 434 can then mark the item entry 436 in the item list 438 as having been sold. The specifics of the sales transaction for the item entry 436, such as price, sales location, store, sales date, or any combination thereof, can also be recorded on the collection server system 402.

The collection server system 402 can include an analytics module 440. The analytics module 440 can be coupled to all of the tracking modules as a source of data to provide statistics for displaying on a device. The statistic can be based on the sales entry 416, the online presence account 420, the promotion entry 424, the payment entry 428, the location entry 432, the item entry 436, or any combination thereof. For example, the device can be the POS terminal 102 of FIG. 1, the vendor system 132 of FIG. 1, the merchant system 126 of FIG. 1, the customer device 136 of FIG. 1, or any combination thereof. The statistic can be for a brand, a store, a buyer account, a promotion program, a product or service, or any combination thereof.

The analytics module 440 can be coupled to the communication module 406 (not shown) to send out a message 442 to an external system, based on the statistics, the sales entry 416, the online presence account 420, the promotion entry 424, the payment entry 428, the location entry 432, the item entry 436, or any combination thereof.

For example, the message 442 can be a payment message or a credit message to the external system based on an identity entry, such as the online presence account 420. The message 442 can be used to make payments to the merchant system 126 of FIG. 1 or the POS terminal 102 of FIG. 1. The credit message can also be for giving an incentive reward to a financial account of the online presence account 420.

For another example, the analytics module 440 can receive a payment message for the item entry 436 from a user device, such as the customer device 136 of FIG. 1. The payment message indicates that a payment has been made for the item entry 436. In response to receiving the payment message and the item entry 436, the analytics module 440 can send the message 442 as a credit message to the POS terminal, such as the POS terminal 102 of FIG. 1, indicating that the transaction has been paid for.

For yet another example, the message 442 can include a real-time price average message for an advertisement system. The analytics module 440 can determine the real-time price message based on the payment entry 428 or the sales entry 416. For example, by storing sales entries such as the sales entry 416 of an item or the item entry 436, the analytics module 440 can determine an average price for the item to send as the message 442 to the advertisement system. The advertisement system can then display the real-time average price on a display to potential customers.

For yet another example, the message 442 can include a recommendation message. The analytics module 440 can store a profile of purchasing pattern based on the transaction entries. The analytics module 440 can also be coupled to an external system, such as the social network system, for determining related item recommendations. The analytics module can then determine a recommended product based on the purchasing pattern or the related item recommendations. The message 442 can include the recommended product to be sent over to the POS terminal or the merchant system.

For yet another example, the message 442 can include an inventory update message. The inventory update can be based on the item entry 436. The quantity of the item entry 436 can be used in the inventory update message to update an inventory list of the CRM system, the merchant system, or the vendor system.

For yet another example, the message 442 can be an instant reward message. The instant reward message can include a message to the POS terminal to print out a coupon immediately. The instant reward message can include a message to an external system to place a rebate, an incentive, a discount, or a credit in a customer's online presence account, such as the online presence account 420, where the customer is identified in the transaction entry by the recognition module 410.

Referring now to FIG. 5, therein is shown a flow chart of a method 500 of operation of the transaction collection system 100 of FIG. 1 in a further embodiment of the present invention. The method 500 includes: initializing a sniff daemon on the POS terminal in a block 502; determining a sales transaction on the POS terminal in a block 504; recording a transaction document of the sales transaction on a memory of the POS terminal in a block 506; collecting the transaction document from the memory with the sniff daemon in a block 508; and providing the transaction document for interpretation on an external system in a block 510.

Here, the transaction document can be, for example, the printable page of FIG. 2 or the transaction record of FIG. 2. The memory can be, for example, the print queue of FIG. 2 or the local transaction store of FIG. 2.

Referring now to FIG. 6, therein is shown a diagrammatic representation of a machine in the example form of a computer system 600 within which a set of instructions, for causing the machine to perform any one or more of the methodologies or modules discussed herein, may be executed.

In the example of FIG. 6, the computer system 600 includes a processor, memory, non-volatile memory, and an interface device. Various common components (e.g., cache memory) are omitted for illustrative simplicity. The computer system 600 is intended to illustrate a hardware device on which any of the components depicted in the example of FIGS. 1-4 (and any other components described in this specification) can be implemented. The computer system 600 can be of any applicable known or convenient type. The components of the computer system 600 can be coupled together via a bus or through some other known or convenient device.

This disclosure contemplates the computer system 600 taking any suitable physical form. As example and not by way of limitation, computer system 600 may be an embedded computer system, a system-on-chip (SOC), a single-board computer system (SBC) (such as, for example, a computer-on-module (COM) or system-on-module (SOM)), a desktop computer system, a laptop or notebook computer system, an interactive kiosk, a mainframe, a mesh of computer systems, a mobile telephone, a personal digital assistant (PDA), a server, or a combination of two or more of these. Where appropriate, computer system 600 may include one or more computer systems 600; be unitary or distributed; span multiple locations; span multiple machines; or reside in a cloud, which may include one or more cloud components in one or more networks. Where appropriate, one or more computer systems 600 may perform without substantial spatial or temporal limitation one or more steps of one or more methods described or illustrated herein. As an example and not by way of limitation, one or more computer systems 600 may perform in real time or in batch mode one or more steps of one or more methods described or illustrated herein. One or more computer systems 600 may perform at different times or at different locations one or more steps of one or more methods described or illustrated herein, where appropriate.

The processor may be, for example, a conventional microprocessor such as an Intel Pentium microprocessor or Motorola power PC microprocessor. One of skill in the relevant art will recognize that the terms “machine-readable (storage) medium” or “computer-readable (storage) medium” include any type of device that is accessible by the processor.

The memory is coupled to the processor by, for example, a bus. The memory can include, by way of example but not limitation, random access memory (RAM), such as dynamic RAM (DRAM) and static RAM (SRAM). The memory can be local, remote, or distributed.

The bus also couples the processor to the non-volatile memory and drive unit. The non-volatile memory is often a magnetic floppy or hard disk, a magnetic-optical disk, an optical disk, a read-only memory (ROM), such as a CD-ROM, EPROM, or EEPROM, a magnetic or optical card, or another form of storage for large amounts of data. Some of this data is often written, by a direct memory access process, into memory during execution of software in the computer 600. The non-volatile storage can be local, remote, or distributed. The non-volatile memory is optional because systems can be created with all applicable data available in memory. A typical computer system will usually include at least a processor, memory, and a device (e.g., a bus) coupling the memory to the processor.

Software is typically stored in the non-volatile memory and/or the drive unit. Indeed, for large programs, it may not even be possible to store the entire program in the memory. Nevertheless, it should be understood that for software to run, if necessary, it is moved to a computer readable location appropriate for processing, and for illustrative purposes, that location is referred to as the memory in this paper. Even when software is moved to the memory for execution, the processor will typically make use of hardware registers to store values associated with the software, and local cache that, ideally, serves to speed up execution. As used herein, a software program is assumed to be stored at any known or convenient location (from non-volatile storage to hardware registers) when the software program is referred to as “implemented in a computer-readable medium.” A processor is considered to be “configured to execute a program” when at least one value associated with the program is stored in a register readable by the processor.

The bus also couples the processor to the network interface device. The interface can include one or more of a modem or network interface. It will be appreciated that a modem or network interface can be considered to be part of the computer system 600. The interface can include an analog modem, isdn modem, cable modem, token ring interface, satellite transmission interface (e.g. “direct PC”), or other interfaces for coupling a computer system to other computer systems. The interface can include one or more input and/or output devices. The I/O devices can include, by way of example but not limitation, a keyboard, a mouse or other pointing device, disk drives, printers, a scanner, and other input and/or output devices, including a display device. The display device can include, by way of example but not limitation, a cathode ray tube (CRT), liquid crystal display (LCD), or some other applicable known or convenient display device. For simplicity, it is assumed that controllers of any devices not depicted in the example of FIG. 6 reside in the interface.

In operation, the computer system 600 can be controlled by operating system software that includes a file management system, such as a disk operating system. One example of operating system software with associated file management system software is the family of operating systems known as Windows® from Microsoft Corporation of Redmond, Wash., and their associated file management systems. Another example of operating system software with its associated file management system software is the Linux operating system and its associated file management system. The file management system is typically stored in the non-volatile memory and/or drive unit and causes the processor to execute the various acts required by the operating system to input and output data and to store data in the memory, including storing files on the non-volatile memory and/or drive unit.

Some portions of the detailed description may be presented in terms of algorithms and symbolic representations of operations on data bits within a computer memory. These algorithmic descriptions and representations are the means used by those skilled in the data processing arts to most effectively convey the substance of their work to others skilled in the art. An algorithm is here, and generally, conceived to be a self-consistent sequence of operations leading to a desired result. The operations are those requiring physical manipulations of physical quantities. Usually, though not necessarily, these quantities take the form of electrical or magnetic signals capable of being stored, transferred, combined, compared, and otherwise manipulated. It has proven convenient at times, principally for reasons of common usage, to refer to these signals as bits, values, elements, symbols, characters, terms, numbers, or the like.

It should be borne in mind, however, that all of these and similar terms are to be associated with the appropriate physical quantities and are merely convenient labels applied to these quantities. Unless specifically stated otherwise as apparent from the following discussion, it is appreciated that throughout the description, discussions utilizing terms such as “processing” or “computing” or “calculating” or “determining” or “displaying” or “generating” or the like, refer to the action and processes of a computer system, or similar electronic computing device, that manipulates and transforms data represented as physical (electronic) quantities within the computer system's registers and memories into other data similarly represented as physical quantities within the computer system memories or registers or other such information storage, transmission or display devices.

The algorithms and displays presented herein are not inherently related to any particular computer or other apparatus. Various general purpose systems may be used with programs in accordance with the teachings herein, or it may prove convenient to construct more specialized apparatus to perform the methods of some embodiments. The required structure for a variety of these systems will appear from the description below. In addition, the techniques are not described with reference to any particular programming language, and various embodiments may thus be implemented using a variety of programming languages.

In alternative embodiments, the machine operates as a standalone device or may be connected (e.g., networked) to other machines. In a networked deployment, the machine may operate in the capacity of a server or a client machine in a client-server network environment, or as a peer machine in a peer-to-peer (or distributed) network environment.

The machine may be a server computer, a client computer, a personal computer (PC), a tablet PC, a laptop computer, a set-top box (STB), a personal digital assistant (PDA), a cellular telephone, an iPhone, a Blackberry, a processor, a telephone, a web appliance, a network router, switch or bridge, or any machine capable of executing a set of instructions (sequential or otherwise) that specify actions to be taken by that machine.

While the machine-readable medium or machine-readable storage medium is shown in an exemplary embodiment to be a single medium, the term “machine-readable medium” and “machine-readable storage medium” should be taken to include a single medium or multiple media (e.g., a centralized or distributed database, and/or associated caches and servers) that store the one or more sets of instructions. The term “machine-readable medium” and “machine-readable storage medium” shall also be taken to include any medium that is capable of storing, encoding or carrying a set of instructions for execution by the machine and that cause the machine to perform any one or more of the methodologies or modules of the presently disclosed technique and innovation.

In general, the routines executed to implement the embodiments of the disclosure, may be implemented as part of an operating system or a specific application, component, program, object, module or sequence of instructions referred to as “computer programs.” The computer programs typically comprise one or more instructions set at various times in various memory and storage devices in a computer, and that, when read and executed by one or more processing units or processors in a computer, cause the computer to perform operations to execute elements involving the various aspects of the disclosure.

Moreover, while embodiments have been described in the context of fully functioning computers and computer systems, those skilled in the art will appreciate that the various embodiments are capable of being distributed as a program product in a variety of forms, and that the disclosure applies equally regardless of the particular type of machine or computer-readable media used to actually effect the distribution.

Further examples of machine-readable storage media, machine-readable media, or computer-readable (storage) media include but are not limited to recordable type media such as volatile and non-volatile memory devices, floppy and other removable disks, hard disk drives, optical disks (e.g., Compact Disk Read-Only Memory (CD ROMS), Digital Versatile Disks, (DVDs), etc.), among others, and transmission type media such as digital and analog communication links.

In some circumstances, operation of a memory device, such as a change in state from a binary one to a binary zero or vice-versa, for example, may comprise a transformation, such as a physical transformation. With particular types of memory devices, such a physical transformation may comprise a physical transformation of an article to a different state or thing. For example, but without limitation, for some types of memory devices, a change in state may involve an accumulation and storage of charge or a release of stored charge. Likewise, in other memory devices, a change of state may comprise a physical change or transformation in magnetic orientation or a physical change or transformation in molecular structure, such as from crystalline to amorphous or vice versa. The foregoing is not intended to be an exhaustive list of all examples in which a change in state for a binary one to a binary zero or vice-versa in a memory device may comprise a transformation, such as a physical transformation. Rather, the foregoing are intended as illustrative examples.

A storage medium typically may be non-transitory or comprise a non-transitory device. In this context, a non-transitory storage medium may include a device that is tangible, meaning that the device has a concrete physical form, although the device may change its physical state. Thus, for example, non-transitory refers to a device remaining tangible despite this change in state.
